Right, it supports AC97.

Ok, I understand that.

When you say "non-ASoC AC'97 code", which file are you referring to ? Is it
sound/pci/ac97/ac97_codec.c ?
If so is there already a table of tuples (AC97_VENDOR_ID1, AC97_VENDOR_ID2) ->
(platform device, platform device data) and a matching mechanism already
available to the ASoC drivers ?
Cheers.
